| | Here is my going around and finally I got there, but not maybe most elegant way as Python did not allow me to take ord from the individual bytes making utf8 letter. So I ended up manipulating the repr of that letter by string manipulation. [CODE]a=unichr(0x3001) b=a.encode('utf8') print b c=repr(b) … |

| | [QUOTE=jcao219;1194537]In my opinion, that assignment is a terrible assignment. I would rather use magic methods to make such a set class, i.e. __iter__, __setitem__, __eq__, __add__, __getitem__[/QUOTE] Also I think using dict for such data type as set is like using lists to implement strings.
